I need to do a query in which I can find all records in a table in which a user enters a search word. The word to be searched for will be a word in a column. If there's a table named solutions and in the table there is a field named description; i need to be able to pull up all records where for example the search word is 'printer' is in the description column. I don't have any code or database structure to show. I first need to know if this can be done. Can someone supply a code snippet example or tell me what SQL keywords will do this, or some pointer?
View 4 RepliesI have developed an Access database and would like to display userid from the user table on the welcome form.
View 1 RepliesI have a database with 3 tables: Student, Unavailability and Duty.The fields for Student are entered in a form I have. One of the fields in Unavailability is filled by a form, the other fields are an autonumber and a foreign key to the Student table.ow I want records in the Duty table to be created and automatically filled in depending on what the values of the fields are in the Student table.For example, If the Boarder field in the Student table is 'yes' then I want the Duty Number field in the Duty table to be '1', '3' and '4'. If it is 'no' then I want the value to be '2' and '5'. I recognize it will have to create several different records to incorporate the different duty numbers for each StudentID. Obviously this will require an if statement, however this is my first time implementing a database with my limited experience with programming and Visual Basic, so I don't know how to refer to the specific fields in a table and set the value of other fields depending on the data in other fields.

I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.

View 2 Repliesi have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

Essentially, what I'm trying to do is build a table of data dynamically on a page that is 3 columns wide by however many long.Working off a Classic ASP example, I've gotten as far as trying that, but not all the records display and they still render on the page as rows instead of columns.[code]I'm not overly certain how to do it, and I'm fairly sure it's probably really simple to do on a view page.My other option is to set a finite amount of records to be created and build the table on the page from that, but I'd much rather do it dynamically.I guess also an alternative option would be to use a repeater control? Though I don't know if this is a control that will work with MVC.
